Abstract

A vehicle body front structure and an impact absorbing method thereof, in which an impact force applied to front side members is efficiently absorbed by an intended deformation of a reinforcing member. A part of the impact force applied to the front side members (12) is received by supporting forces in axial directions of a dash cross member (20) and a pillar brace (22). A
recess (24) is provided in the dash cross member (20) in the portion thereof connected with the front side member (12). A recess (26) is provided in the pillar brace (22) in the portion thereof connected with the front side member (12). Due to the dash cross member (20) and the pillar brace (22) compressively deforming in the axial directions starting at these recesses (24), (26), the dash cross member (20) and the pillar brace (22) absorb impact force which is applied to the front side members (12) from the front of the vehicle.
